This study evaluated the effect of a calculus scaling gel (SofScale(TM
)) on time and ease of the scaling procedure in a double-blind, split-
mouth clinical study of 32 subjects. The Volpe-Manhold calculus index
was used to quantify the distribution and amount of calculus depositio
n on the lingual aspect of the mandibular 6 anterior teeth at baseline
. The gel was applied directly to the calculus and subgingivally to th
e area to be scaled. Pre- and post-treatment gingival and stain indice
s were taken. Operator and subject questionnaires were completed immed
iately after treatment to determine ease of the scaling procedure. Res
ults were analyzed with paired t-tests. The time difference in scaling
between the product and placebo side was not significant. This study
found that SofScale(TM) is safe to gingival tissues and does not promo
te tooth sensitivity. However, this study did not find significant dif
ferences in scaling time between product and placebo when using a 2-mi
nute gel contact time.
